nenn cooune DEVICE.

SPECIFICATION forming part of Letters Patent No. 789,594, dated May 9. 1905.

Application filed July 28,1904. Serial No. 218,545.

To (LZZ who/1t it mm/y concern.

Be it known that I, J AMES DOUGLASS, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in Beer-Cooling Devices, of which the following is a description, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention relates to devices for cooling liquids as they are delivered from a storagereceptacle, and is particularly adapted for use in connection with the delivery of beer from the keg or barrel. In serving beer it has been a usual custom to cool the beer in the keg by packing ice about it. It takes considerable time to cool the beer in this way and. the cost of the ice is considerable, and there are other objections. Another way has been to draw the beer through a cooling device, and this has been found to be satisfactory as long as the cooler can be kept clean. In the devices for this purpose, so far as I am aware, the matter of cleaning has been a serious difficulty, it being necessary either to depend. on forcing water or other cleansing lluid through the device, which uncertain, or to take the device to pieces, which takes considerable time.

The device of my invention consists in a construction in which the main parts of the device are permanently secured in position and the passages for the beer are straight and easily gotten. at for cleaning by merely dd taching a removable cap.

Referring to the drawings, Figure l. is a perspective view of my improved cooler. Fig. 2 is a vertical section through one of the groups of pipes. Fig. 3 is a horizontal detailsectional view of one end of the groups of pipes.

111 the drawings, A a pan or box, preferably open on top and either open at bottom or having bottom B, as shown, the four walls of the pan or box being alone the essential parts. Extending from side to side of the pan or box are groups of cooling-pipes C of comparatively small diameter. There are preferably two of these groups of coolingpipes; but more or less than this number may be used, if desired. The pipes of each group are arranged within a circle and are preferably secured in holes formed in circular heads D, provided with flange D and located in circular openings E, formed in the sides of the pan or box A. of the heads is secured the end of a diagonal pipe F, leading to the opposite head D of the other group of cooling-pipes, and from the head I) of the rear group of cooling-pipes opposite to that to which the diagonal pipe F is connected an inlet-pipe G leads to the keg or other source of supply. From the head I) of the forward group of cooling-pipes opposite to that to which the diagonal pipe F is connected leads an outlet-pipe ll, provided with a faucet or cork l The inlet and outlet pipes are within the sides of the pan or box 1 All of the pipes are straight with the exception of the inlet and outlet pipes, which are slightly curved near the points at which. they are connected with the heads D.

Rei'novable caps K are arranged to be de tachably secured to the flanges D of the heads D. The heads may be faced off on the sides to form an octagonal or other nut, so that they may be readily grasped by a wrench. or spanner. A packing ll is preferably provided between the flange of the cap and. the head to which it is secured. The faucet or cock is preferably made detachable from the outlet-pipe.

WVhen the caps K are in position and. the inlet-pipe connected with the keg or other source of supply, ice is packed in this pan or box A about the pipes, and a block of ice may be placed on top of the box. As soon as the faucet is opened the beer enters the interior of the cap, covering the head to which the inlet-pi pe leads, an d passes through the cooling-phpcs of the rear group into the in terior of the opposite cap and then through the diagonal pipeF into the interior of one of the caps of the forward groups and then through the cooling-pipes of the forward group into the opposite cap, from which it flows to the outlet. The c(. olingpipes C are preferably of such size that the pipes of each group with the caps will hold about one glass or a little over, so that as a glass of beer is In one of the holes of one' drawn from the forward group of pipes a sufficient quantity to fill a second glass is immediately supplied from the rear group of pipes to the forward group. As the groups of cooling-pipes present a large surface for the cooling action of the ice, it will be found that successive glasses of thoroughly-cooled beer may be drawn with reasonable rapidity.

In order to clean the cooling device, the caps are unscrewed, and as the cooling-pipes and diagonal pipes are straight they may be thoroughly cleaned by running a brush through them from either end. The inlet and outlet pipes are either substantially straight or at least have but slight curvature and are readily cleaned.

In the construction above described it will be noted that the caps are solid that is, no pipes are directly connected with them and consequently they may be removed and replaced without disconnecting any of the pipes.

It will be understood that changes inform and arrangement may be made without departing from the spirit of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cooling device the combination of a box or pan adapted to contain a cooling medium, heads carried by the sides of the box or pan, straight cooling-pipes having open ends secured at their ends in the heads and extending from side to side of the box or pan, an inlet-pipe connected to one of said heads and arranged within the box or pan, an outlet-pipe connected to another of said heads and arranged within the box or pan, and imperforate caps covering the heads.

2. In a cooling device the combination of a pan or box adapted to contain a cooling medium, cooling-pipes open at their ends, arranged in groups within the pan or box and extendingfrom side to side thereof, removable caps secured over the ends of the groups of pipes, a diagonal pipe within the pan or box communicating with the interior of the cap at one end of one group of cooling-pipes and with the interior of the cap at the opposite end of the other group, and inlet and outlet pipes communicating with the interior of the caps.

In testimony whereof I afiix my signature in presence of two witnesses.
